Note: This is an experimental project under active development. Please do not submit merge or commit requests at this time.

ATHENA is a real-time collaborative code editor system, enabling multiple developers to edit code files simultaneously with instant synchronization—similar to Google Docs, but for code. The core value is zero-friction collaboration, eliminating merge conflicts during active editing. Text synchronization is achieved using Operational Transformation (OT), a proven algorithm for consistent document state across clients, even with concurrent edits.

Key features:

• Real-time bidirectional communication via WebSockets
• Operational Transformation for text consistency
• Multi-user sessions and presence indicators
• Professional code editor integration (Monaco)

The system architecture includes a Go server (sync hub), WebSocket clients, and optional Redis for session persistence.

Foundation: WebSocket Communication

• Build a Go server to handle WebSocket connections
• Implement basic message passing (send/receive JSON)
• Manage connection lifecycle and active connection pool
• Route messages between clients in the same session
• Design a message protocol for join, leave, broadcast, and keepalive (ping/pong)
• Ensure robust error handling and logging

Testing includes connecting with browser WebSocket APIs, using CLI tools, and simulating multiple clients.

Currently in Phase 1: building core functionality and validating speed improvements on real repositories.
